Specification of Letters Patent. Patented J une 6, 1922.

Application filed September 14, 1921. Serial No. 500,560.

T 0 all whom it may concern: 4 Be it known that I, WILLIAM S. BENSON, acitizen of the United States, and a resident of Newark, in the county ofEssex and State of New Jersey, have invented a new and ImprovedElectromagneticWave Bath, of which the following is a full, clear, andexact description. The. object of this invention is to provide anelectro-magnetic Wave bath for treating the cells of the body and whichhas in conjunction therewith means for treating the skin to ,destroygerms and'means for applying electricity to the difierent parts of the Afurther object is the provision 'oi'an BlGCtIG-Hlitgllfiiilc wave bathprovided with means for varying the strength of the magnetic torcebetween certain limits at a rate equal to the heart beats of thepatient. These objects are accomplished by providing a container andmeans for'causing lines of magnetic force, which are continu allyreversing their direction, to flow therethrough, and means for varyingthe strength of this magnetic force, and means inconjunction with thecontainer means for generating light. rays which have a germic daleffect in different skin diseases, and means for applying electricitydirectly to different parts of the body.

These and other objects of-the inventionwill be more clearly understoodfrom the following detailed description and accompanying drawings.

Referring to the above-mentionedfigures; this apparatus as shown in Fiure 4 consists of a container 10 which 1s made of cylindrical shape' Thi'container is made of a non-magnetic material such as brass. The reasonfor this will appear later in the specification. Located around thisnonmagnetic container is a layer of mica or some other insulatingmaterial 11. Wound about the container over the insulating material i aconductor of electricity 12 of some satis-- factory type to form anelectromagnetic field within the container. This-coil is made up of. agreat number of turns dependingupon the-strength of the magnetic forcethat-1t lating material 13 and the various layersare encased by means ofan iron cylinder 14.

Surrounding the elec- This encasing member might possibly be made ofother material than iron but this is most'satisfcactory for the purpose.The cylinder, 14 is supported on a plurality of legs 15.

Located inside of the container 10 is a lining 16 which carries aplurality of lamp sockets 17 which are connected with a source ofelectric current in any usual manner. Mounted in these sockets are lamps18. These lamps are selected from amongst those that generate light raysof different colors in the spectrum. it is well known that light rays ofcertain colors are destructive to germs and these lights are providedfor generating rays for treating skin diseases.

n of vibration. the various colors of the spectrum are employed throughthe medium of colored lights. These different colored vibrations producedifierent efiects, such as thermal, germicidal, stimulative and seda-'tive., The s ecial feature of application of these vibratlons of coloris that they will also be alternating to conform to the normal ordertobe able to employ distinct rates i beat of the heart of the patientbeing treated.

Referring to Figures 6, 7 and 8, a regulator for controlling the amountof current passing throu h the coil about the container is shown. InTigure 8 a diagram of the connections is disclosed as containing coils21, 22, 23, 24, which, when alternating current is used, operate, whenin circuit as choke coils to cut down the strength of the current. Theterminals of these coils are connected to contact points 25, 2e, 27, as,ea, 30, 31, a2, 33, 34 by means of wires 36 to 45, inclusive, as shownin the diagram. The conductor 12 which is wound about the container 10has one terminal connected to the contact point 25 by means of aconductor 48, and the other terminal to a terminal of a source of supplyof alternating current by means of the conductor 47. The other terminalof the source of supply is connected by means of a conductor 46 to theshaft 49. Mounted on the shaft 49 is an arm which serves to connect itto any one of the contact points 25 to 34, inclusive. It will be seenthat one or all of the choke coils 21 to 24, inclusive, may be connectedin series with the conductor 12 in order to vary the current flowingthrough the said conductor. As the arm 35 rotates in a counter-clockwisedirection one coil is added for each ste until the arm reaches contactpoint 30. fter that until the arm reaches contact point 34 one coil iscut out upon each step thus increasing the amount of current flowingthrough the conductor 12. Thus for every rotation of the arm 35 thecurrent flowing in the conductor 12 is decreased from the maximum amountto the minimum which flows when all the coils are connected in serieswith the conductor and then increased to the maximum which flows" whenall the coils are cut out of the circuit. These coils are enclosed in abox 54 and may have a core 53 extending throu h them. The arm 35 isrotated by means 0 a motor 51connected to a pulley 50 by a belt 52. Thepulley 50 is fixed to the shaft 49. The speed of this may be controlledso as to rotate the arm 35 at any desired speed. With such a device itis possible to vary the current flowing in the conductor 12' to certainlimits periodically and by properly controlling the speed of the motoror the gear ratio between the motor and rotating'contact arm the numberof periodical variations may be made to conform to the number of heartbeats of the patient. Any number of coils might be provided in theregulator to obtain a more gradual or a more abrupt increase or decreasein current in the conductor 12.

The maximum current flowing in the conductor 12 is obtained when the arm35 engages the contact point 25 or the con- '49, arm 35, con uctor 12andback to conductor 47 or through conductor 46, shaft 49, arm 35,contact point 34, conductors 45 and 36, conductor 12 and back throughconductor 47. The minimum amount of current flows when the arm 35contacts with either of the contact points 29 or 30. When the arm 35contacts with the contact point 29 the current flows through conductor46, shaft 49, arm 35, contact point 29, the coils 24 to 21, inclusive,conductor 12 and back through the conductor 47. As the arm 35 is movedover contact points 25 to 29 the current flowing in the conductor 12 isgradually decreased and as the arm 35 moves over contact points 30 to 34the current flowing is gradually increased. As the current flows throughconductor 12 lines of magnetic force are created about the conductor.These lines of magnetic force permeate the space within the containerand are reversed in direction every time the curent flowin in theconductor reverses its direction. T e container 10 is made ofnon-magnetic material so that the lines of magnetic force will permeatethe space in the container instead of flowing through the walls of thecontainer.

One end of the casing 14 has a cap' 55 fitted thereon. This cap 55 has aplurality of holes 56 extending therethrough. .Mounted in each hole is ashaft 57 to which is connected a core 58 of an inductance coil 59. Thisinductance coil is rovided with two terminals 60 and 61 which may beconnected with suitable body electrodes, for applying electricitydirectly to the different parts of the body of the patient. The inducedcurrent in the inductance coil 59 may be varied by adjusting theposition of the coil. If it is desired to obtain a greater current thecoil is moved inward into the portion of the container surrounded b theconductor 12 as indicated in dotted lines in Figure 2. This current canbe utilized to gently exercise each and every muscle of the bod byapplying it directly to cause wave-1i e contractions and relaxations ofthe body tissue. The special construction of this apparatus enables theregulation of the current'to such a fine degree that the Wave-like imulses are absolutely painless and non-irritating. Another feature ofapplication of this current is'that its strength will periodically varybetween certain predetermined limits ac-' cording as the current isvaried in conductor 12, and as above stated the current in is bathedwith alternating electrical vibrations. -c

A certain amount of heat Wlll ordlnarrly be developed by the magneticcoil 12 and the lamps 18 will also supply their proportionate heat tothe interior of the treating cell or container so that the patient willbe subjected to the effect of heat, as well as the application of light,magnetism and current electricity. Ordinarily, the lights will beconnected in circuit with and governed by the controller so that thelight and heat, as well as the magnetism and current electricity will beapplied in the form of waves of more or less gradually increasing anddecreasing intensity. lVhen these so-called waves of heat. light,magnetism and ourrentelectricity are brought into time with .the heartbeats of the patient, asby properly controlling the speed of thecontroller motor, a most effective treatment results. Further it isfound that if the heart beats are abnormal this ccndition can beimprovedby timing the waves to what would be normal for the person undertreatment, this exerting a corrective effect and serving to restoreconditions to the normal. The applied current electricity and theelectromagnetic flux both being of periodically varying intensity, oo-
